Tokusou Sentai Dekaranger (特捜戦隊デカレンジャー, Tokusō Sentai Dekarenjā) is a Japanese tokusatsu series that serves as the 28th installment in the Super Sentai franchise and the 16th entry in the Heisei era. In an iteration of the planet Earth where extraterrestrial contact is possible, the S.P.D. (Special Police Dekaranger) battles alien criminals collectively called "Alienizers".

Main characters

Dekarangers

The eponymous Dekarangers are members of the S.P.D.'s Earth unit who utilize the SP License (SPライセンス, Esu Pī Raisensu) in Change Mode (チェンジモード, Chenji Mōdo) to transform and protect Earth from intergalactic criminals called Alienizers.

The primary Dekarangers can also utilize their SP Licenses in Phone Mode (フォンモード, Fon Mōdo) to communicate with each other, analyze items pertaining to a case they are working, and summon their Deka Machines to battle Kaijuki; and in Judgment Mode (ジャッジメントモード, Jajjimento Mōdo) to determine a criminal's innocence in a particular crime and whether the criminal can be approved for termination, or "deletion". In battle, the Dekarangers wield varying D-Arms (ディーアームズ, Dī Āmuzu). After undergoing further training, the primary Dekarangers gain the ability to transform into their S.W.A.T. Modes (スワットモード, Suwatto Mōdo), which grants the use of the high-powered D-Revolver (ディーリボルバー, Dī Riborubā) machine gun.

Ban

Banban Akaza (赤座 伴番, Akaza Banban), also known as "Ban" (バン), is a hot-headed, chaotic, loudmouthed, bad tempered, yet fiercely loyal and friendly rookie member of the S.P.D., who previously trained in space before being assigned to lead S.P.D.'s Earth unit in the field as Deka Red (デカレッド, Deka Reddo). While he joins the newly created Fire Squad as an elite officer in the series finale, he occasionally returns to help his original team. Initially having an immature personality, he slowly matures throughout the series.

In battle, Ban is a practitioner of the fictional space martial art Juu Kune Do (ジュウクンドー, Jū Kun Dō), which blends unarmed martial arts skills with gunplay. Additionally, he wields the twin D-Magnum (ディーマグナム, Dī Magunamu) handguns, which he can combine to form the Hybrid Magnum (ハイブリッドマグナム, Haiburiddo Magunamu) and perform the Magnum Execution (マグナムエクスキュージョン, Magunamu Ekusukyūjon), Moonsault Shot (ムーンサルトショット, Mūnsaruto Shotto), Endless Shot (エンドレスショット, Endoresu Shotto), Hurricane Shot (ハリケーンショット, Harikēn Shotto), and Moonsault Galaxy Shot (ムーンサルトギャラクシーショット, Mūnsaruto Gyarakushī Shotto) attacks. While wielding Doggie Kruger's D-Sword Vega, Ban can perform the Akaza Sword Art: Raijin Sword (赤座剣法・雷神剣, Akaza Kenpō Raijin Ken) attack and the Impulse Vega Slash (インパルスベガスラッシュ, Inparusu Bega Surasshu) attack.

After joining the Fire Squad and during the events of Mahō Sentai Magiranger vs. Dekaranger, Ban acquires a variant of the SP License called the Fire Squad License (ファイヤースクワッドライセンス, Faiyā Sukuwaddo Raisensu), which allows him to transform the robot police dog Murphy into armor to assume Battlizer Mode (バトライザーモード, Batoriza Mōdo). In this form, he gains superhuman agility, increased fighting capability, a rocket booster pack, siren lasers, and a sword/rifle hybrid, which allows him to perform the Battlize Fire Drive (バトライズファイヤードライブ, Batoraizu Faiyā Doraibu) finisher. As of the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Ban has acquired a red-colored S.W.A.T. Mode vest to signify his membership in the Fire Squad.

Ban is portrayed by Ryuji Sainei (載寧 龍二, Sainei Ryūji).

Hoji

Houji Tomas (戸増 宝児, Tomasu Hōji), also known simply as "Hoji" (ホージー, Hōjī), is the professional, yet arrogant and stubborn, second-in-command and sniper of the team who serves as Deka Blue (デカブルー, Deka Burū). While he is reserved about his personal life and shows little emotion to prevent both from interfering with his work, he has a tendency to blurt out English phrases such as "Perfect!", "Unbelievable!", and "Super cool!". Due to their differing personalities, Hoji clashes with Ban early in the series, though Hoji slowly warms up to, and becomes friends with, Ban. Later in the series, Hoji applies for a gold badge promotion from the Tokkyou division, but ultimately refuses it due to a personal tragedy. In the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Hoji goes undercover as a shut-in after Kruger's seeming turn to crime to help Ban and Sen-chan restore their leader's reputation.

In battle, Hoji wields the D-Knuckle (ディーナックル, Dī Nakkuru) and the D-Rod (ディーロッド, Dī Roddo) baton, the latter of which he can use to perform the Blue Finish (ブルーフィニッシュ, Burū Finisshu) attack. He can also combine his D-Arms to form the D-Sniper (ディースナイパー, Dī Sunaipā) rifle.

Hoji is portrayed by Tsuyoshi Hayashi (林 剛史, Hayashi Tsuyoshi).

Sen-chan

Senichi Enari (江成 仙一, Enari Sen'ichi), also known as "Sen-chan" (センちゃん), is the eccentric, yet calmest and smartest member, of the team, due in part to his ability to think things through and being able to do his best thinking while in a handstand, which he considers his "thinking pose". Sen-chan serves as Deka Green (デカグリーン, Deka Gurīn). The oldest of seven siblings from a poor family, he displays nycto- and claustrophobia after accidentally falling into a well when he was a child. He was subsequently rescued by a policeman, which inspired him to take up police work. Despite his usually calm demeanor, he is said to be scary when angered. He also displays a crush on teammate Umeko, but avoids showing it publicly. In the crossover film Mahō Sentai Magiranger vs. Dekaranger, they moved in together. In the succeeding Super Sentai series Uchu Sentai Kyuranger, they became engaged.

In battle, Sen-chan also wields a D-Knuckle and D-Rod, the latter of which he can use to perform the Green Crash (グリーンクラッシュ, Gurīn Kurasshu) attack. Similarly to Hoji, Sen-chan can combine his D-Arms to form the D-Blaster (ディーブラスター, Dī Burasutā) rifle.

Sen-chan is portrayed by Yousuke Itou (伊藤 陽佑, Itō Yōsuke). As a child, he is portrayed by Kengo Tajima (田島 健吾, Tajima Kengo).

Jasmine

Marika Reimon (礼紋 茉莉花, Reimon Marika), also known as "Jasmine" (ジャスミン, Jasumin), is a calm and collected psychic, or "ESPer", who serves as Deka Yellow (デカイエロー, Deka Ierō). In the past, she suffered from depression over her then-inability to control her abilities and contemplated suicide by allowing an Alienizer to kill her. However, she was rescued and recruited by Doggie Kruger. In the present, she is good friends with teammate Umeko, with whom she forms a tag-team called the Twin Cam Angels (ツインカム・エンジェル, Tsuin Kamu Enjeru). As of the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Jasmine is married and has a son named Taiga (大我).

Jasmine's ESPer abilities allow her to pick up on sensory impressions of others by handling an object connected to them or visiting a location her target has been to, though overuse of her powers exhausts her. To control her powers, she wears gloves. Furthermore, as a result of breast-feeding her son during Dekaranger: 10 Years After, Jasmine has gained the ability to teleport herself to any part of the universe. In the crossover film Mahou Sentai Magiranger vs. Dekaranger, she displays the ability to break the fourth wall.

Unlike the other primary Dekarangers, Jasmine can use her SP License to perform the Mirage Dimension (ミラージュディメンション, Mirāju Dimenshon) attack. In battle, she wields a D-Knuckle and the D-Stick (ディースティック, Dī Sutikku) jitte, which comes equipped with Zeni Bomb (ゼニボム, Zeni Bomu) coins and can combine with her D-Knuckle to form the D-Shot (ディーショット, Dī Shotto) handgun. Together with Umeko and their D-Shots, Jasmine can perform the Twin Cam Shot (ツインカムショット, Tsuin Kamu Shotto) attack.

Jasmine is portrayed by Ayumi Kinoshita (木下 あゆ美, Kinoshita Ayumi). As a child, she is portrayed by Risa Asagi (浅黄 理紗, Asagi Risa).

Umeko

Koume Kodou (胡堂 小梅, Kodō Koume), also known as "Umeko" (ウメコ), is a ditzy, yet kind-hearted and perky, member of the team who serves as Deka Pink (デカピンク, Deka Pinku), though she frequently claims to be the field leader. Throughout the series, she spends every moment she can in a bubble bath with her three rubber ducks, Umeyo, Umenosuke, and Umegoro. After learning of Sen-chan's feelings for her, she moves in with him, as of the crossover film Mahō Sentai Magiranger vs. Dekaranger, and becomes engaged to him as of the succeeding Super Sentai series Uchu Sentai Kyuranger.

Unlike the other primary Dekarangers, Umeko can use her SP License's Masquerade Mode to instantaneously change her outfit for disguise purposes. In battle, she also wields a D-Knuckle and D-Stick, which she can combine to form the D-Shot and perform the Twin Cam Shot alongside Jasmine.

Umeko is portrayed by Mika Kikuchi (菊地 美香, Kikuchi Mika).

Tetsu

Tekkan Aira (姶良 鉄幹, Aira Tekkan), also known as "Tetsu" (テツ), is an elite officer from S.P.D.'s Tokkyou (特キョウ, Tokkyō) division, serving as the white-colored Deka Break (デカブレイク, Deka Bureiku), who was sent to Earth to delete the Hells Siblings and staying on Earth to help the Earth unit. As a child, Tetsu's parents were killed by an Alienizer named Genio, before Tetsu was taken off-world and raised by S.P.D. Due in part to this, he is initially distant from the other Dekarangers, but eventually befriends them.

Unlike the primary Dekarangers, Tetsu wields the Bracethrottle (ブレスロットル, Buresurottoru), which functions as an SP License, can double as a life-support system and a fire extinguisher, and allows him to perform a variety of specialized punches. In battle, he is a practitioner of the fictional fighting style of Justice Fist Accel Blow (正拳アクセルブロー, Seiken Akuseru Burō), a martial art that all Tokkyou officers train in, to better handle their equipment and battle particularly deadly Alienizers.

During the events of the crossover film GoGo Sentai Boukenger vs. Super Sentai, Tetsu, among other veteran Sentai warriors, is recruited by Boukenger member Eiji Takaoka to help him rescue his allies and defeat the Time Demon, Chronos. In the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Tetsu becomes the new head of S.P.D.'s Earth unit, following his predecessor Doggie Kruger being framed for murder, and assists in clearing Kruger's name.

Recurring characters

S.P.D.

The Special Police Dekaranger (スペシャル・ポリス・デカレンジャー, Supesharu Porisu Dekarenjā), abbreviated as S.P.D. (エス・ピー・ディー, Esu Pī Dī), is an intergalactic police force that ensures all aliens abide by intergalactic laws, using advanced extraterrestrial technology, such as Deka Metal, which is used in the construction of their Dekarangers' suits. Their Space Prosecution Office headquarters is based on Planet Gowashichoru, which is affected by a form of time dilation called the Sion Morse effect, causing it to move faster than the rest of the universe. When the Dekarangers judge an Alienizer, an eight-month trial, which is the equivalent of ten seconds on Earth, takes place on Gowashichoru to determine the criminal's innocence or guilt in a particular crime.

Doggie Kruger

Anubian Doggie Kruger (アヌビス星人ドギー・クルーガー, Anubisu Seijin Dogī Kurūgā), also known as "Boss" (ボス, Bosu) to several of his subordinates, is from Planet Anubis and is the tough-yet-honorable superintendent of the Space Police's Metropolitan Police, as well as chief of its Earth branch. While operating as a Dekaranger in his younger years, he earned a legendary reputation as "Hell's Guard Dog" (地獄の番犬, Jigoku no Banken), due in part to his willingness to do anything to save those he cares about. Despite this, he displays feelings for his assistant Swan and panics whenever he hears she has an admirer.

During the events of the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Kruger investigated the alleged corruption of his superior Kight Reidlich, and was framed for murder and held captive for two years before his team rescues him in the present. Soon after, Kruger admits his feelings for Swan.

In battle, Kruger is a practitioner of the Galaxy Sword-Style (銀河一刀流, Ginga Ittō-ryū), and learned the style's secret technique, the Vega Impulse (ベガインパルス, Bega Inparusu). Though he is capable of destroying 100 foes without being defeated, he suffered from a spinal problem that caused him to miss once every 2000 attacks until being cured by Abaranger member and chiropractor Yukito Sanjyo. Additionally, using a variant of the SP License called the Master License (マスターライセンス, Masutā Raisensu), Kruger can transform into the black-colored Deka Master (デカマスター, Deka Masutā). While transformed, he wields the D-Sword Vega (ディーソード・ベガ, Dī Sōdo Bega), which possesses a gun function and allows him to perform the Vega Tornado Slash (ベガトルネードスラッシュ, Bega Torunēdo Surasshu) attack and the Vega Slash (ベガスラッシュ, Bega Surasshu) and Vega Impulse finishers.

Doggie Kruger is voiced by Tetsu Inada (稲田 徹, Inada Tetsu).

Swan Shiratori

Cignian Swan Shiratori (チーニョ星人 白鳥 スワン, Chīnyo Seijin Shiratori Suwan) is Doggie Kruger's intellectually and technologically gifted assistant from Planet Cigno who provides the Dekarangers with their arsenal. While she possesses a variant of the SP License called the Swan License (スワンライセンス, Suwan Raisensu), which grants her the ability to transform into the orange-colored Deka Swan (デカスワン, Deka Suwan), she has a personal policy to only do so once every four years, except for emergencies.

As Deka Swan, she can perform the Swan Illusion (スワンイリュージョン, Suwan Iryūjon) attack and the Swan Rainbow (スワンレインボー, Suwan Reinbō) finisher.

Swan Shiratori is portrayed by Mako Ishino (石野 真子, Ishino Mako).

Murphy K-9 (マーフィーK9, Māfī Kē Nain) is a "talented robot police dog" that possesses the "latest model ultra-performance...

He is loyal to the Dekarangers, Umeko especially, and can also transform into the D-Bazooka (ディーバズーカ, Dī Bazūka) via the Key Bone (キーボーン, Kī Bōn) to help the Dekarangers delete Alienizers. As of the crossover film Mahō Sentai Magiranger vs. Dekaranger, Murphy was transferred to the Fire Squad and upgraded with the ability to transform into Ban's Battlizer Mode.

Modes. Buntar is voiced by Naoki Kusumi (楠見 尚己, Kusumi Naoki).
• Lumierian Lisa Teagle (リュミエル星人リサ・ティーゲル, Ryumieru Seijin Risa Tīgeru): The chief of the Tokkyou Division's first squad from Planet Lumiere, and Tetsu's mentor, who believes that the perfect officer must be passionless to be efficient. Additionally, using her own Bracethrottle, she can transform into the silver-colored Deka Bright (デカブライト, Deka Buraito). After coming to Earth, she initially intended to take Tetsu back for straying from her teachings, but decides against that after seeing him fight, realizing that passion can be a positive trait for an officer. Lisa Teagle is portrayed by Mie Nanamori (七森 美江, Nanamori Mie).
• Leonian Gyoku Rou (レオン星人ギョク・ロウ, Reon Seijin Gyoku Rō): Ban's leonine predecessor, from Planet Leon, who was meant to become Deka Red on Earth, but was badly injured while protecting Jasmine and Hoji from an Alienizer called Terry X, which seemingly forced Rou to retire. In reality, he was tasked by Numa-O to go underground and prepare an elite team called the Fire Squad (ファイヤースクワッド, Faiyā Sukuwaddo). In the present, after being forced out of hiding when Terry X resurfaces, Rou recruits Ban in recognition of his fiery passion and drive for crime-fighting.

Alienizers

Space Criminal Alienizers (宇宙犯罪者アリエナイザー, Uchū Hanzaisha Arienaizā) is an umbrella term that S.P.D. gives to aliens that commit various crimes on Earth and other planets. Unlike most monsters in the Super Sentai franchise, many of the Alienizers pilot giant robots called Kaijuki (怪重機, Kaijūki, "Monstrous Heavy Industrial Machines"), which are usually provided by Agent Abrella.

Agent Abrella

Rainian Agent Abrella (レイン星人エージェント・アブレラ, Rein Seijin Ējento Aburera) is a bat-themed arms dealer from Planet Rain, and an infamous figure in the intergalactic black market, who is known for causing wars in seven galaxies, destroying billions of lives in the process. As his homeworld's name suggests, it is perpetually raining, forcing him to wear a special helmet that produces an artificial rainy environment to sustain himself on other worlds. After arriving on Earth, he offers his services, as well as Mechanoids and Kaijuki, to his fellow Alienizers for the right price. Initially staying in the shadows, Abrella gathers information on the Deka Base from clients who have successfully infiltrated it and escaped with their lives, while planning to eventually realize his desire for a "world of...currency and crime". After eventually making his presence known to the Dekarangers and losing a Browgoul he intended to raise to them, Abrella starts taking their interference personally and launches a failed smear campaign against them. Following this, Abrella takes advantage of the Dekarangers' fight with the Alienizer Jellyfis to break four Alienizers out of prison and lead them in taking over the Deka Base. From there, he uses Deka Base Robo to go on a rampage, lure the bulk of S.P.D.'s forces to Earth, and uses their planetary forcefield against them. While the Dekarangers eventually retake Deka Base Robo and use the D-Bazooka to delete Abrella, as of the crossover film Mahō Sentai Magiranger vs. Dekaranger he has been succeeded by his pupil, Agent X,.

In the direct-to-video anniversary special Tokusou Sentai Dekaranger: 10 Years After, Kight Reidlich has cloned a giant version of Abrella that he keeps on Planet Highgord to help him fight the Dekarangers. However, Clone Abrella is killed by Dekaranger Robo piloted by Deka Break.

Throughout the series, Abrella pilots the following Kaijuki as part of his schemes:

• Big Drawer II (ビグドローワー2, Bigu Dorōwā Tsū): A chest-of-drawers-themed Super Kaijuki that he uses in his smear campaign against the Dekarangers before it is destroyed by Deka Base Robo.
• Abtrex (アブトレックス, Abutorekkusu): Abrella's personal Kaijuki that can assume the Abtrailer (アブトレーラー, Abutorērā) drill-vehicle mode. He tasks the Alienizer Angorl with using it to attack the Deka Base and damage Dekaranger Robo before the Kaijuki is destroyed by Deka Bike Robo and the Deka Wing Cannon. During the events of Mahō Sentai Magiranger vs. Dekaranger, Agent X pilots the succeeding model, Abotrex (アボトレックス, Abotorekkusu), before it is blasted into space by Magi Legend and the Deka Wing Cannon, and is destroyed by Magi King, Dekaranger Robo, Travelion, and Deka Bike Robo.

Abrella is voiced by Ryūsei Nakao (中尾 隆聖, Nakao Ryūsei).

• Batsuroids (バーツロイド, Bātsuroido): Planet-themed androids that lead the Anaroids and wield hand-mounted guns and, later, swords. Throughout the series, the Batsuroids pilot Kaijuki such as the chest of drawers-themed Super Kaijuki (超巨大怪重機, Chōkyodai Kaijūki) Big Drawer (ビグドローワー, Bigu Dorōwā), which is capable of storing buildings, the flight-capable Hunter Jet 2 (ハンタージェット2, Hantā Jetto Tsū), the angel-themed Megaroria (メガロリア), and the knight-themed Knight Chaser (ナイトチェイサー, Naito Cheisā) before being destroyed by Deka Base Robo, confiscated by the Dekarangers for use in a sting operation, destroyed by Deka Bike Robo, and destroyed by Super Dekaranger Robo respectively. The Batsuroids are voiced by Katsumi Shiono and Yuuki Anai.

Minor Alienizers

• Lovelian Balance (ラブーリ星人バラン・スー, Rabūri Seijin Baran Sū): A giant non-humanoid alien from Planet Lovely who smuggled the Fan Crusher's control mechanism for Don Moyaida, who subsequently betrayed him.

• Diamantian Don Moyaida (ディアマンテ星人ドン・モヤイダ, Diamante Seijin Don Moyaida): A diamond-themed criminal from Planet Diamante who is charged with infanticide, vehicular manslaughter, and the theft of terrestrial resources.
